The piranha is found in the rivers and lakes of South America. It is a meat-eating fish with long, triangular, razor-sharp teeth. It is not very big, but when hungry it can be bold and savage. Some piranhas are silver with orange undersides. Others are almost totally black. All have strong jaws. The name “piranha” comes from the Portuguese words for “fish” and “tooth.”
There are 20 different kinds of piranhas in the Amazon River. The red-bellied piranha is the most famous and has the strongest jaws and the sharpest teeth. These fish hunts in schools of more than 100 fish. Piranhas have excellent hearing.
